Answer: See below
Explanation:
p-(p+20) = 4(p-5) + 3p
p-p-20 = 4p - 20 + 3p
-20 = 7p -20
40 = 7p
40/7 = p
From oldest to youngest: I, B, F, M, R, H.
Explanation:
On the picture we can see several layers of rock. Some of the layers have not been disturbed, so the principle of superposition can be applied to them. Some of the layer though have been disturbed by geological processes, so the layers are not at the same level because of it. On top of it, there is also an intrusion that has managed to further cause disturbance through all of the layers.
- The layer I is the oldest, and it is the basis of the others.
- Layer B has formed next, and after that layer F.
- These three layers have been influenced by the formation of fault, where one of their sides has been moving up relative to the other, while the other has been moving down relative to the other.
- Layer M is younger layer, and it can easily be seen as it totally covers the layer F below it.
- On top is layer R, which is the youngest of them all (the layers), and the one that comes out on the surface.
- Layer H is not really a layer, but it is an intrusion, which has formed after magma managed to cut through all the layers and later solidify. It is the youngest formation.

Answer and Explanation:
It is true fact that organic matter in soil diminishes with time yet it is unseemly to utilize this information for lab manual since we make heaps of changes to recoup natural issue in the dirt before going for another period of editing. Notwithstanding when the yield is reaped, the buildup of the previous harvest goes about as a natural fuel for the following yield. Here and there when we develop vegetable harvest, it rather adds minerals to the soil.
But if there is comparison between earlier soil and current soil, I figure it would be nearly increasingly precise for the as of late cleared soil since here, we can quantify the exhaustion of natural issue plainly. while the soil which had been cultivated and prepared for horticulture before, there probably come different changes because of enormous number of factors.l
